| 摘 要： | 本文研究了宇宙弦中超导电流的磁效应以及度规函数和超导电流之间的关系。研究表明:超导宇宙弦外部时空相当于一种磁化率为μ(r)的磁介质;当光线经过超导宇宙弦时,产生偏折。同时,在弱场近似下,也讨论了超导宇宙弦的引力场度规和当光线经过宇宙弦时所产生的偏折角。

| Abstract: | We show that the magnetic effect for superconducting current in cosmic string and the rilations between the metric parameters and the superconducting current. It has been shown that external space-time of superconducting cosmic string is epuivalent to a kind of magnetic-medium with permeability μ(r) and when light passes through the string, it will be difected an angle. Beside, we also discuss the metric of superconducting cosmic string and the defecting angle of light in weak field approximation. |
